ASSIG'NOR TO FIRM NEUERIBUBGSGHE VERVJALTUNGSGESELLSCHAFT' G. M. B. H.,OF COLOGNE-ON-THE-RHINE, GEBIVIANY MACHINE FOR MAKING CIGARETTESApplication filed July 17, 1930, Serial No. 468,697, and in GermanyDecember 3, 1928.

My invention relates to improvements in machines for making cigarettes,and more particularly in the apparatus for feeding the tobacco.

Heretofore tobacco feeding apparatus for machines for manufacturingcigarettes have been constructed in which the tobacco contained within areceptacle is made loose and distributed at its surface by means of arotary roller or drum provided with spikes. In one construction a rotarydrum has been provided the bearings of which are stationary relativelyto the tobacco receptacle, and which is provided with spikes or needlessadapted to be retracted into the drum while rotating the same, aplurality of rollers being provided within the receptacle. In anotherconstruction a rotary drum provided with spikes has been provided abovethe feed roller, for supplying a layer of tobacco of uniform thicknessand compactness. These are objectionable for the reason that the tobaccois distributed and made loose at one part of the receptacle.

The object of the improvements is to provide a machine of this class inwhich a roller carrying spikes or needles is adapted to be moved to orfro across the surface of the tobacco in horizontal or substantiallyhorizontal direction with its axis parallel.

For the purpose of explaining the invention an example embodying thesame has been shown in the accompanying drawing in which the samereference characters have been used in all the views to indicatecorresponding parts. In said drawing,

Fig. 1 is a diagrammatical sectional elevation showing the feedingmechanism, and

Fig. 2 is a liagram showing the electric circuit controlling thesignalling device.

W'ithin receptacle containing the tobacco to be supplied to thecigarette making devices of the machine a drum or roller provided withspikes or needles 16 is rotatably mounted with its shaft 14 on twoparallel levers 13 and 13 keyed to a rock shaft 20, the said roller ordrum being parallel to a roller 1 provided with needles and rotating inthe direction of the arrow as and a roller 2 rotating in the directionof the arrow 3 and cooperating with the roller 1 for stripping thetobacco therefrom. The rock shaft is mounted by means of brackets 12 ona suitable part of the machine for example on aboard 6 rockingly mountedon a shaft 11. The said board is adapted to be rocked to and fro from ashaft 9 through the intermediary-of a crank 8 and a link 7, the saidshaft being adapted to be rotated the direction of the arrow 2 means ofsuitable gearing such as a pulley The spikes or needles 16 of the drumor roller 15 are inclined rearwardly as com pared to the direction ofthe'rotation of the drum indicated in Fig. 1 by the arrow 0, and suchrotary movement is imparted to the drum from a shaft 36 by means of abelt 3 trained on a pulley 4 keyed to the shaft 36 and a pulley 5 keyedto a shaft 28, a chain and sprocket gearing comprising a sprocket wheel27 keyed to the shaft 28, a sprocket wheel and a chain 26 trained on thesaid sprocket wheels, a chain and sprocket mechanism'comprising asprocket wheel 23 connected with the sprocket wheel 25, a sprocket wheel21 rotatable on the sh aft 26 and a chain 22 trained on the sprocketwheels 23 and 21 and a chain and sprocket mechanism com prising asprocket wheel 19 connected with the sprocket wheel 21, a sprocket wheel17 keyed to the shaft 1 1 and achain 18 trained on the sprocket wheels19 and 17. To the board 6 or another part of the machine an arm 29is'secured by means of which the rocking movement of the levers 13downwardly is I controlled and preferably the said arm 29 is shiftablymounted for regulating the extent of the downward movement of the levers13. On arms 136 made integral with the levers 13 a brush 30 is mountedwhich is disposed substantially radially of the roller 15 and extends anarm 37 secured to or made integral with the lovers 13 or 13 a weightedbody 31 is mounted. Above the said body. contacts 33 and 34 are fixed toan insulating block 31 which are included in a circuit comprising abattery 38 and a signalling device 35, the said contacts 33 and 3 1being normally out of ento the surface of the drum. On

gagement with each other for opening the circuit.

1 The operation of the apparatus is as folows:

By the crank 8 and the link 7 rocking movement is imparted to the board6 so that the roller 15 is moved to and fro and substantially inhorizontal direction across the surface of the tobacco andsimultaneously it is rotated in the direction of the arrow o. Therebythe tobacco within the receptacle is distributed and made loose. Thebrush 3O combs any tobacco which might stick between the spikes of theroller 15 from the said spikes, and it prevents transmission of thetobacco from the left hand part of the receptacle to the right and tothe drum 2. The roller 15 bears on the surface of the tobacco with apressure controlled by the weighted body 31 adapted to be shifted on thearm 37, and the arm 29 limits the downward movement of the said rolleras the tobacco is removed from the receptacle. If the roller has sunk toa certain position the weighted body 31 engages the contact 33 andforces the same into engagement with the contact 34 and to thesignalling apparatus such as a lamp 35.

r If desired a gate or the like controlling the supply of tobacco to thereceptacle may be provided.

I claim 1. Means for supplying tobacco to cigarette making machines,comprising a rotary drum located above the tobacco being supplied andadapted to loosen said tobacco, and means for moving said drum acrossthe surface of said tobacco substantially in a hori zontal direction.

2. Means for supplying tobacco to cigarette making machines, comprisinga receptacle for tobacco, a rotary drum located above the tobacco andadapted to loosen the latter, a frame carrying said drum and rockablymounted on one of the walls of said receptacle, and means for rockingsaid wall in a direction to cause the drum to move across the surface ofthe tobacco.

3. Means for supplying tobacco to cigarette making machines, comprisinga receptacle having one wall thereof movable, a rotary drum locatedabove the tobacco being supplied and adapted to loosen said tobacco, aframe carrying said drum and rockably mounted on said movable wall,means for rocking said wall in a direction to cause the drum tomove'across the surface of the tobacco, and a weighted body connectedwith said frame and shiftable thereon for regulating the pressure of thedrum on the tobacco.

4. Means for supplying tobacco to cigarette making machines, comprisinga receptacle having one wall thereof movable, a rotary drum locatedabove the tobacco being supplied to loosen the same, a frame Carryingsaid drum and rockably mounted on said signature.
